JCB Laboratories (JCB) is issuing a recall of six lots of sterile drug products to the user level due to concerns of sterility assurance following a recent inspection by the U.S. Food and Drug Administration of Front Range Laboratories of Loveland, Colo., one of the contract testing labs used by JCB.

JCB has not received any reports of adverse events related to this recall to date. If there is microbial contamination in products intended to be sterile, patients are at risk for serious, potentially life-threatening infections.

The recalled products were distributed to outpatient dialysis clinics in multiple states from July 8, 2013, through Aug. 20, 2013.

In the recent inspection of Front Range Labs, the FDA stated it "observed that methods used by Front Range to assess sterility and other qualities (e.g., strength and stability) may have resulted in pharmacies receiving inaccurate laboratory test results. FDA has concerns that results obtained from Front Range are not reliable. FDA recommends that pharmacies not use this firm for sterility and other quality attributes testing at this time."

Out of an abundance of caution, JCB has discontinued its relationship with Front Range and is now testing products at a different laboratory.

"Our top priority is to protect patient safety," said Brian Williamson, PharmD, President and CEO of JCB Laboratories. "We have never had to issue a recall, but we believe this action is a reflection of our tradition of total transparency and our commitment to the highest quality standards. We regret any inconvenience this recall may cause our valued customers."

JCB has begun notifying its customers by telephone, email, fax and mail. To return product or request assistance related to this recall, users should contact JCB Laboratories at 316-773-0405 Monday through Friday, between 8:00 a.m. and 5:00 p.m. CDT.

Consumers should contact their physician or health care provider if they have experienced any problems that may be related to taking or using this drug product. Any problems may be reported to the FDA's MedWatch program via:
